Is your Central Heating System vented or sealed
Before you buy a central heating system you need to understand what type of system and central heating boiler you will want. Below you will find an outline of the main forms of central heating system presently traded. The form of central thinking system taken will determine the type of heating boiler to be fitted.
Air conditioning systems are not yet a stock feature in homes whereas every northern European family is built with a form of central heating. The majority of new houses that are being built in this day and age are built with a Central Heating System.
Heating is vital, particularly in wintertime. No one would deny how a dwelling house is transformed when we install an efficient heating system. Another crucial role for the central heating system is to create hot water. As heating and hot water are essentials your system needs to be reliable. Out of sight everyday operation without unpredicted breakdowns is a standard requirement of any central heating system.
Pumped systems and sealed central heating systems are the two primary forms.
Expect to find a pumped/vented central heating system as they are the most frequent. The main deviation you will see is that this form of heating system in addition to the hot water cylinder is that it has an expansion tank. The tank makes way for any water expansion that is induced by the heating process. The attic is most normally used to house the expansion tank as it needs to be high in the house.
As thinking develops sealed systems are now more commonly being installed in homes. The water expansion tank can be dispensed with in a sealed central heating system. The mains water is used to supply the sealed Central Heating System. This removes the requirement for any pipe work or central heating water tanks in the loft, you will get the following advantages when acquiring a sealed system:
- frozen winter copper piping from copper pipes in the attic it is now eradicated
- fewer components mean reduced purchase costs
- reduces the risk of leaking
- reduced risk of airlocks, corrosion and sludge as there isn’t a chance of air being drawn down into the system through open vents as the system is sealed
It is familiar for the water supply pressure to change and that this is dealt with by incorporating a pressure vessel. Safety valves open if the interior pressure is too high. Other automated valves open to allow the interior water to be topped up if it drops to low.
